I presume the question is "what is 10 percent of minus 100"10% x -100 = -10
90%
4000 - 10% = 90% of 4000 = 4000*90/100 = 3600
2500 - 10% = 90% of 2500 = 2500*90/100 = 2250
99.99 minus 10 percent of 99.99 is 89.991
85%
9.75 - 10% = 90% [left] of 9.75 = 9.75*90/100 = 8.775
10% minus 32 is -31.9
100 minus 110 is -10.
700 - 10% = 700 x (1 - (10/100)) = 700 x 0.9 = 630
The answer is 540. Working: 600 divided by 100 times (100-10)percen (%). = 540. so the total is 540
10/100 x 100 = 10 percent Therefore, 10 is 10 percent of 100.
